But Paula Patton and Chrissy Teigen took it a step further on Saturday as they both wore outrageously deep plunging necklines to the Pre-Grammy gala in Los Angeles.

Showdown: Chrissy Teigen and Paula Patton wore plunging necklines to the Pre-Grammy party with John Legend and Robin Thicke in Los Angeles on Saturday
